I have reached the point where I have had enough of the crap MMCS unit and looking to upgrade it. Now I've read every thread I could find on the subject and it's doing my head in.

I've got a 2012 NW with the Rockford Fosgate system and would like to keep the speakers, amp, sub and steering wheel controls with only the head unit being updated. The only one I can find is the Dig Options Masten Android unit but the reviews aren't that good.

So has anyone successfully updated to another unit such as Kenwood, Pioneer, etc...?

How did you go with your Upgrade? Did you wire it up yourself or use a Aerpro style harness. I'm doing mine at the moment and have purchased Aerpro harnesses x 4 and I am flat out trying to figure out how the hell you get 4 harnesses with similar plugs into 1 factory harness! Did you have the Map / Rockford version of MMCS ?

I gave up as it all got too hard. Spoke to a car stereo place who could upgrade to a Pioneer unit but the total cost was $1300. I like my music but not that much.

Once you have the adapter connecting the wires up is relatively straightforward. It looks super complicated but one wire at a time following the instructions it is doable for the amateur.

I found a ground point using one of the existing bolts to the metal frame that sits behind the head unit.

I bought a new surround off ebay for about $30 which is easy to swap over from the original.

At the same time I replaced the reverse camera. This was the hardest part. A real mission running the wires through the rubber gommets in the rear door and through to back tail light. Had to remove rear door panel and side panels which I really didnt want to do. The camera cable was run through these then up and slipped inside the roof lining rubber.

The head unit required a trigger wire for the reverse camera. I found the info on this site. It sits in the centre console coming out of a large white plug located on the left by the 4wd selector. The wire is the 3rd in from the left and is red/green in colour - slightly thicker than the others.
